Abstract
The utility model provides a novel porta hepatis blood flow blocking band which comprises a limiting tube and a blocking band body. The limiting tube is provided with two through holes and a winding column of a cross-shaped structure. The end of the winding column is provided with a locating clamp device composed of two clamping plates. The corresponding portions of the two clamping plates are respectively provided with two grooves matched with the cross section of the blocking band body in shape. One ends of the two clamping plates are connected through hinges, and the other ends of the two clamping plates are locked through buckles. The cross section of the blocking band body is round. The cross sections of the grooves in the clamping plates are of semi-cylinder shapes. The cross section of the blocking band body is matched with the cross sections of channels formed through the grooves in the clamping plates in size. The end of the blocking band body is provided with a spherical spring tightening buckle. The novel porta hepatis blood flow blocking band can be effectively prevented from loosening and slipping, the portal vein or the hepatic artery of the liver can be effectively prevented from rotating or twisting, and the risk of damaging the portal vein or the hepatic artery of the liver is reduced.
Description
Technical field
This utility model relates to a kind of hepatobiliary surgery medical apparatus and instruments, is specifically related to a kind of novel pringle maneuver band.
Background technology
Hepatic portal occlusion Shu Shi Genneral Surgery operates front in order to reduce step hemorrhage and that do in art to liver.Why so do not direct row operation technique.Because liver nearly 1000ml blood per minute passes through.High flow capacity like this, high-speed, and also liver blood fortune is abundant.Complex structure.See that common hepatic duct road cast moulds just can know.The sponge that liver does just as piece blood.No matter how how you do.How to touch.Not blocking blood confession, is all hemorrhage.Hepatic portal occlusion step is to need through portal vein, the Hepatic artery etc. of liver the blood vessel of blocking with aseptic blocking-up band etc., then clamps blocking-up band, blocks into hepatic blood flow.Reduce hemorrhage in operation on liver and use.
At present, on hospital clinical, mostly use easy pringle maneuver band, it is made up of a hollow pipe and a blocking-up band, when operation, blocking-up band is walked around after portal vein or Hepatic artery, two of blocking-up band is passed from pipe, after then manpower is strained, clamps blocking-up band fixing by vascular forceps at pipe place.This easy pringle maneuver technology, the one, when fixing by vascular forceps, blocking-up band is very easy to slippage, gets loose, and often needs repeatedly to repeat to be strained and fixed when operation, has wasted operating time; The 2nd, when liver blocking-up operation, operative space itself is just very limited, then fixes by vascular forceps, and vascular forceps has taken the space of operation, has reduced the space of operation, and doctor operates very inconvenient.
In addition, also there is the hepatic portal blocking belt patented product that some are special, as the patent No.: CN200920290565.2, Granted publication number: CN201572134U, denomination of invention: the disposable use hepatic portal blocking belt of adjustable locking-type; The patent No.: CN201020577437.9, Granted publication number: CN201814620U, denomination of invention: can relax self-locking type hepatic portal blocking belt; And with the similar product of above-mentioned patented product, these products are using when band blocking-up, be all will blocking-up band one end as stiff end, the other end of blocking-up band is carried out to tractive.Such tractive mode has caused under the frictional force effect of blocking-up band, can cause the portal vein of liver or Hepatic artery rotation, distortion, causes blood vessel injury.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes a kind of novel pringle maneuver band, comprise position-limiting tube, blocking-up band, it is characterized in that: on described position-limiting tube except being provided with two through holes, also be provided with winding post, winding post is cross structure, winding post termination is provided with positioning clamp appts, described positioning clamp appts is made up of two clamping plates, two clamping plates be respectively provided with to corresponding position two with the grooves that match with shape of cross section of blocking-up, one end of two clamping plates is connected through the hinge, the other end is locked by hasp, when two clamping plates locking, groove on clamping plate forms two passes, blocking-up band passes from passage, described blocking-up band cross section is circular, groove cross section on described clamping plate is semicircle cylindricality, the cross section size of the passage that the cross section of blocking-up band and clamping plate upper groove form matches, the end of described blocking-up band is provided with spherical spring and buckles, described blocking-up band is walked around winding post, the passage forming from clamping plate groove passes being fixedly clamped and locating, buckle blocking-up band is clamped with spherical spring at clamping plate place.
beneficial effect:this utility model pringle maneuver band, the one: when use, after blocking-up band has been wrapped in winding post, clamp by clamping device, make blocking-up band can landing, get loose, than vascular forceps fixed form, increased operative space.The 2nd: when blocking-up band is carried out to tractive, need to carry out tractive to the two ends of blocking-up band simultaneously, thus, can not cause the portal vein of liver or Hepatic artery rotation, distortion, reduce portal vein or the hepatic arterial damage risk of liver.
